Chame nsead tu age 06-17 Experiment 8: Molar Mass of a Volatile Liquid Purpose To determine the molar mass of a pure substance we need to find out (a) the number of moles in a given sample, and (b) the mass of the same sample. Molar mass is then: mass divided by moles Introduction Using the ideal gas equation, PV= nRT, we can determine the number of moles (n) of gas or vapor under measured conditions of pressure (P), volume...

Prepare For It! Prelab Question A student weighs a flask, foil cover, and rubber band and finds the mass is 74.95 g. He then adds about 5 mL to the flask and then heats the flask in a boiling water bath (100.0°C) to evaporate all of the volatile liquid. Once the flask is removed from the water bath and cooled, the collected gas condenses into a liquid. The mass of the flask, foil cover, rubber band, and condensed liquid is...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
Molecular Weight of a Volatile Liquid In this experiment, an amount of liquid more than sufficient to fill the flask when vaporized is placed in a flask of measured volume and mass. The flask is then heated in a boiling...

THE MOLAR MASS OF A VOLATILE LIQUID 1. A foil-covered flask was found to have a mass of 161.38 have a mass of 167.38 g. A volatile liquid was placed L00.0°C at a barometric pressure of 743.8 mm Hg. The foil-covered inside and heated to 100.0°C at a barometric press flask containing the vapor had a mass the molar mass of this volatile liquid. 's the vapor had a mass of 167.71 g and a volume of 147.0 mL. Calculate...

Two methods were descibed for determining the volume of the
flask used for the molar mass determination. Which method will give
a more precise determination of the volume? Why?
When two acceptable determinations of the weight of vapor needed to fill the flask have been obtained, remove the foil cover from the flask (do not discard) and clean out the flask. Fill the flask to the very rim with tap water, cover with the foil cover, and weigh the flask,...
